DETAILED DESCRIPTION

In order to further illustrate the principle and structure of thedisclosure, the embodiments of the disclosure will be described indetail with reference to the accompanying drawings.

In an embodiment, the disclosure provides an air conditioner apparatuswhich is an all-in-one machine. Compared with the structure in which theindoor unit and the outdoor unit of the traditional air conditionerapparatus are independent of each other, the indoor unit and the outdoorunit of the air conditioner apparatus of this embodiment are integratedin the same apparatus, that is, the evaporation device and thecondensation device are integrated in the same apparatus. The all-in-onemachine can exhaust the hot air generated therein through the exhausttube.

Specifically, as shown in FIG. 1 and FIG. 2, FIG. 1 is a schematicperspective view of an air conditioner apparatus in an embodiment, andFIG. 2 is a section view of FIG. 1, the air conditioner apparatus 100includes an evaporation device 10, a condensation device 20, arefrigerant compressor 30, a refrigerant filter 40 and a throttlingdevice 50. The refrigerant compressor 30, the condensation device 20,the refrigerant filter 40 and the throttling device 50 are sealed in aclosed box 101, and the evaporation device 10 is arranged outside theclosed box 101. An air inlet port 102 and an exhaust port 103 are openedon the closed box 101, and the air inlet port 102 is connected to airinlet of the condensation device 20, the exhaust port 103 is connect tothe air outlet of the condensation device 20. An exhaust tube isconnected to the exhaust port 103, and is long enough so that the portof the exhaust tube can extend outdoors, so as to discharge the hot airafter heat exchange with the condensation device 20 to outside. Acontrol panel 105 is further arranged on the closed box 101, and acontrol circuit electrically connected to the control panel 105 isfurther arranged in the closed box 101.

The evaporation device 10 and the condensation device 20 are verticallyfixed on the same seat body 104, so that the evaporation device 10 andthe condensation device 20 are integrated together to form an integratedmachine.

The above-mentioned seat body 104 and the above-mentioned closed box 101can be integrally formed.

As shown in FIG. 3, FIG. 3 is a cross-sectional view of the airconditioner apparatus in an embodiment. The evaporation device 10 isroughly cylindrical, with a fan 61 arranged on the top, and an airflowopening 10 a is arranged on the bottom end away from the fan 61 forairflow in and out. The fan 61 may be a suction fan or a blower. Whenthe fan 61 is a blower, the fan 61 sucks in the air in the atmospherefrom the top of the evaporation device 10 and sends it into theevaporation device 10. After the heat exchange is completed, thetemperature of the air decreases and blows out into the room from theairflow opening 10 a. When the fan 61 is a suction fan, the fan 61 sucksin air from the bottom of the evaporation device 10 through the airflowopening 10 a. The sucked air is cooled in the evaporation device 10, andthe cooled air finally flows out into the room through the fan outlet atthe top.

It can be understood that, in an embodiment, the fan 61 may also bearranged at the bottom of the evaporation device 10, and in this case,the airflow opening for air flow in and out is arranged at the top.

At least one of the evaporation device 10 and the condensation device 20comprises the heat exchange structure of the disclosure. The specificstructure of the heat exchange structure is described in detail below bytaking the heat exchange structure included in the evaporation device asan example.

Specifically, in an embodiment, as shown in FIG. 4 and FIG. 5, FIG. 4 isa front view of a heat exchange structure in an embodiment of thedisclosure, and FIG. 5 is a schematic cross-sectional view along A-A inFIG. 4. The heat exchange structure 1 a includes a housing 11, and aplurality of medium tubes 12 and a plurality of fins 13 arranged in thehousing 11. The inner of each medium tube 12 is formed with a mediumcirculating channel 121.

The housing 11 includes an upper end opening and a lower end opening.Air flows in from the upper end opening and flows out from the lower endopening. In actual applications, the airflow can also flow in from thelower end opening of the housing 11 and flow out from the upper endopening. The housing 11 has a circular tube shape. In other embodiments,the housing 11 may also have a square tube shape or other shape.

The housing 11 can be integrally molded by extrusion with the mediumtube 12 and the fins 13. In addition, the housing 11 can also be formedindependently of the medium tube 12 and the fins 13, and the medium tube12 and the fins 13 are integrally molded by extrusion, that is, themedium tube 12 and the fin 13 are formed and then the housing 11 is putthereon.

The housing 11, the medium tube 12 and the fin 13 can be integrallymolded by metal extrusion. The metal can be aluminum alloy or othermaterials with good heat transfer. This molding method makes thedistribution of the medium tube 12 and the fin 13 more uniform andcompact. Compared with the welding molding method, the gap size betweenthe fins 13 can also become smaller, and to a certain extent, the heatexchange area is increased, thereby improving heat exchange efficiency;and the integrated molding method increases the accuracy of devicemolding and reduces the difficulty of manufacturing. In this way, theheat exchange device can be designed to be smaller, achieving thepurpose of reducing the size and meeting people's desire forminiaturization. In addition, the integrated molding method can alsoimprove production efficiency and reduce costs.

The heat exchange structure 1 a includes a plurality of medium tubes 12and a plurality of fins 13 arranged in the housing 11. One medium tube12 of the plurality of the medium tubes 12 is located at the geometriccenter of the heat exchange device, and the remaining medium tubes 12are radially distributed around the geometric center. The fins 13 areconnected between the medium tubes 12. Arranging the medium tube 12 inthis way can improve the heat exchange efficiency between the medium inthe medium tube 12 and the fins, and increase the range of the airflowheating or cooling. In addition, the arrangement of the plurality of themedium tubes 12 increases the amount of medium entering the heatexchange device, which means that it can exchange heat with a largeramount of airflow, thereby improving efficiency and reducing time.

It should be noted that the geometric center of the heat exchangestructure 1 a can be determined according to its cross-sectional shape.For example, in FIGS. 4 and 5, the heat exchange device is cylindricalas a whole, whose cross-section is circular, and whose geometric centeris the center of the circular section. For another example, if the crosssection of the heat exchange device is square or rectangular, itsgeometric center is the intersection of two diagonal lines. And so on,they are not listed in detail herein.

Furthermore, as shown in FIG. 5, the plurality of medium tubes 12 aredistributed on a plurality of circumferences with different radii aroundthe center of the circular cross section of the heat exchange structure1 a. Specifically, with the medium tube 12 in the center as the center,the remaining medium tubes 12 are arrayed to a plurality of circles withdifferent radii, and a plurality of medium tubes 12 are arranged atequal intervals or unequal intervals on each circle. With thisarrangement, the medium tubes 12 can be evenly distributed at eachposition of the heat exchange structure 1 a, so that the medium in themedium tube 12 can evenly exchange heat with the airflow, and ensurethat the temperature of the airflow after heat exchange is uniform.

Each medium tube 12 forms a medium circulating channel 121. Due to thelayout of the medium tube 12, the medium circulating channels 121 can bedivided into multiple groups. Each group of medium circulating channels121 are distributed at intervals in the circumferential direction aroundthe center which is the center of the heat exchange structure 1 a, anddifferent groups of medium circulating channels 121 are distributed oncircles with different radii.

Each medium circulating channel 121 extends in a height direction of thehousing 11, and runs from an upper end of the housing 11 through to alower end of the housing 11. As a result, the heat exchange efficiencyper unit area is increased.

The fin 13 extends in the height direction of the medium tube 12 andextends from the upper end to the lower end of the medium tube 12. Inthis way, the heat dissipation area can be increased and the heattransfer efficiency can further be improved. The outer wall of eachmedium tube 12 is connected with the fin 13. Specifically, the fin 13 isconnected to the medium tube 12 located at the geometric center andextends in the radial direction thereof, that is, the fin 13 can extendfrom the medium tube 12 located at the geometric center to the housing11.

Specifically, a plurality of fins 13 are arranged between the mediumcirculating channels 121 and between the housing 11 and the mediumcirculating channel 121. A gap 131 for airflow passage is formed betweenthe fins 13. The fins 13 are distributed radially with the center lineof the housing 11 as the center (or with the medium tube 12 located atthe geometry center as the center), and are evenly arranged on the outerperiphery of each medium circulating channel 121. This distribution ofthe fins 13 increase the number of fins 13 arranged per unit area andincrease the integration of the fins 13 per unit area, thereby improvingthe heat transfer efficiency per unit area. As a result, the evaporationdevice and/or the condensation device can be designed to be smaller,greatly reducing the size of the air conditioner apparatus.

The medium circulating channels 121 may be communicated in series or inparallel through connecting tubes. In one embodiment, as shown in FIG.4, a connecting tube 141 is provided at the lower end of the housing 11,and the connecting tube 141 can be communicated in parallel with aplurality of medium circulating channels 121 along the radial directionof the housing 11 at the lower end of the housing 11. As shown in FIG. 6and FIG. 7, FIG. 6 is a top view of FIG. 4, and FIG. 7 is a bottom viewof FIG. 4. A refrigerant medium inlet 151 is arranged at the lower endof the housing 11, which is communicated with the connecting tube 141 atthe lower end of the housing 11, and the refrigerant medium flows intothe medium circulating channels 121 connected to the connecting tube 141through the refrigerant medium inlet 151 and the connecting tube 141.The medium circulating channels 121 that are not communicated with theconnecting tube 141 can be communicated with the medium circulatingchannels 121 through which the refrigerant medium passes by anotherconnecting tube 142, and finally there is refrigerant medium circulatingin each medium circulating channel 121. A refrigerant medium outlet 152is arranged at the lower end of the housing 11, through which therefrigerant medium in the medium circulating channel 121 flows out.

In an embodiment, the heat exchange structure 1 a may be provided withone refrigerant medium inlet and one refrigerant medium outlet, and themedium circulating channel 121 in the housing 11 are communicated inseries through connecting tubes.

In an embodiment, the medium circulating channels 121 may becommunicated in parallel. Specifically, the upper end and the lower endof the housing of the heat exchange structure 1 a are respectivelyprovided with an inlet manifold and an outlet manifold. The upper portof each medium circulating channel 121 is communicated with the inletmanifold, and the lower port of each medium circulating channel 121 iscommunicated with the outlet manifold. The refrigerant medium flows fromthe inlet manifold into each medium circulating channel 121, passesthrough each medium circulating channel 121 and then converges in theoutlet manifold, and finally flows out from the outlet manifold.

The location and quantity of the refrigerant medium outlet andrefrigerant medium inlet can be changed according to the actualapplication. The communication between the medium circulating channelsmay be serial communication, or parallel communication, or partialserial communication and partial parallel communication.

In addition, the number of medium circulating channels can be determinedaccording to actual applications. For example, the number of mediumcirculating channels is more than two, which has a better coolingeffect.

In another embodiment, as shown in FIG. 8, FIG. 8 is a schematiccross-sectional view of a heat exchange device in another embodiment.The heat exchange structure 1 b is integrally molded by extrusion, andthe heat exchange structure 1 b is formed with at least one mediumcirculating channel 161, and a plurality of fins 17 are formed on theouter periphery of the medium circulating channel 161, and arranged atintervals to form gaps 18 allowing airflows to pass therethrough.

The heat exchange structure 1 b has a cylindrical shape as a whole andits cross-section is circular.

As shown in FIG. 8, the heat exchange structure 1 b includes a pluralityof medium circulating channels 161. A part of the medium circulatingchannels 161 are formed by the medium tubes 16, and the other part ofthe medium circulating channels 161 are formed by the fins 17.

The heat exchange structure 1 b includes a medium tube 16 located at thegeometric center of the heat exchange structure 1 b. It can beunderstood that the heat exchange structure 1 b may include a pluralityof medium tubes 16, one of which is located at the geometric center ofthe heat exchange structure 1 b. The other part of the mediumcirculating channels 161 formed by the fins 17 is distributed in acircumference around the medium tube 16 at the geometric center.

A plurality of the fins 17 are arranged on the outer peripheral wall ofthe medium tube 16 at intervals. The fins 17 extend in the heightdirection of the medium tube 16 and extend in the radial direction fromthe medium tube 16 located at the geometric center.

The fins 17 are fork-shaped or pliers-shaped. The fork-shaped fin 171includes a rod part 1711 and a bifurcation part 1712. The rod part 1711is connected with the medium tube 16 located at the geometric center,and the bifurcation part 1712 is connected with the rod part 1711. Thepliers-shaped fin 172 includes two oppositely arranged special-shapedfins 1721, 1722. The end of the special-shaped fin 1721, 1722 away fromthe geometric center is arc-shaped, and the arc-shaped ends of the twospecial-shaped fins 1721, 1722 enclose to form the above-mentionedmedium circulating channel 161. The medium circulating channel 161extends from the upper end of the fin 17 to the lower end of the fin 17,that is, the medium circulating channel 161 formed by the enclosing ofthe fins 17 and the medium circulating channel 161 formed by the mediumtubes 16 are equal in height. Here, the fins 17 are arranged in a forkshape or a pincer shape to increase the heat exchange area and improvethe heat exchange efficiency.

As shown in FIG. 8, the pliers-shaped fin 172 includes four fins 172,which are respectively located directly above, directly below, directlyleft and directly right of the center of the circular cross section.However, it is not limited to this, and the number and position of thepliers-shaped fins 172 can be varied.

As mentioned above, the pliers-shaped fins 172 can form a mediumcirculating channel 161 for the passage of the medium. In addition, themedium circulating channel 161 formed by the pliers-shaped fins 172 canalso be configured to be inserted a support rod so that the heatexchange device can be supported on the ground or on other equipment,for example, in FIG. 8, the medium circulating channels 161 locateddirectly on the left and right are configured to circulate the media,and the support rods are inserted into the two medium circulatingchannels 161 located directly above and directly below for supporting.In this way, the medium circulating channel 161 has two functions, andcan be configured to be inserted a support rod when not configured forcirculation of the medium.

Continuing to refer to FIG. 8, the inner wall of the medium tube 16protrudes inwardly to form a plurality of protrusions 162, and theplurality of protrusions 162 are circumferentially distributed along theinner wall of the medium tube 16. In this way, the heat exchange area ofthe medium tube 16 can be increased, and the heat exchange efficiencycan be improved.

Further, as shown in FIG. 9, FIG. 9 is a schematic cross-sectional of aheat exchange device provided with housing in another embodiment, theheat exchange structure 1 b further comprises a housing 19 that coversthe medium tube 16 and fins 17. The housing 19 is integrally molded byextrusion with the medium tube 16 and the fins 17, or the medium tube 16and the fins 17 are molded by extrusion and the housing 19 is formedindependently of the medium tube 16 and the fins 17.

The housing 19, the medium tube 16 and the fins 17 can be all made ofaluminum alloy. The aluminum alloy material has good thermalconductivity, thereby can improve the heat exchange efficiency of theheat exchange structure 1 b.

Both the condensation device 20 and the evaporation device 10 can adoptthe heat exchange structure of any one of the above-mentionedembodiments or a structure with equivalent changes made according to theheat exchange structure. The cooling medium circulating in the mediumcirculating channel 121 is a refrigerant, for example, a cooling mediumsuch as Tetrafluoroethane or Freon. When the condensation device 20adopts the above-mentioned heat exchange structure 1 a (or 1 b), therefrigerant which is passed into the medium circulating channel 121 isthe high-temperature and high-pressure refrigerant. A fan 61 is arrangedon the end of the condensation device 20, and sweeps the outer wall ofthe medium circulating channel 121 and the fin 13 to take away heat, sothat the temperature of the refrigerant in the medium circulatingchannel 121 is lowered, achieving the purpose of cooling therefrigerant. When the evaporation device 10 adopts the above heatexchange structure 1 a (or 1 b), the refrigerated refrigerant is passedinto the medium circulating channel 121, and the air to be cooled ispassed into the housing 11 to exchange heat with the refrigerant in themedium circulating channel 121. The heat is absorbed and the airtemperature drops, which achieves the purpose of cooling the air.

Both the evaporation device 10 and the condensation device 20 adopt theabove heat exchange structure, so that the evaporation device 10 and thecondensation device 20 can be designed to be smaller, thus greatlyreducing the size of the air conditioner apparatus.

In the above embodiment, the evaporation device 10 and the condensationdevice 20 both adopt the above-mentioned heat exchange structure torealize heat exchange, but it is not limited to this, and it may alsoone of the evaporation device 10 and the condensation device 20 thatadopts the above-mentioned heat exchange structure. In other words,another device that does not adopt the above-mentioned heat exchangestructure can adopt the traditional heat exchange structure to realizeheat exchange.

The evaporation device 10 is configured to cool the indoor air. Asmentioned above, under the action of the fan 61, the outside wind entersthe evaporation device 10 and passes through the gap 131 between thefins 13 from the upper end of the housing 11 to the lower end of thehousing 11 (or from the lower end of the housing 11 to the upper end ofthe housing 11), contacts the outer wall of the medium circulatingchannel 121 for heat exchange. The refrigerant in the medium circulatingchannel 121 absorbs heat and vaporizes. The temperature of the absorbedair decreases and the absorbed air flows out of the housing 11.

The refrigerant connecting tube 10 b at the inlet end of the evaporationdevice 10 is connected to the refrigerant tube of the throttling device50, and the refrigerant connecting tube 10 c at the outlet end of theevaporation device 10 is connected to the refrigerant tube of therefrigerant compressor 30 to input the vaporized refrigerant to therefrigerant compressor 30 for compression.

The refrigerant connecting tube 20 b at theoutlet end of the condensation device 20 is connected to the refrigeranttube of the refrigerant filter 40. The refrigerant filter 40 isconfigured to filter impurities in the medium-temperature andhigh-pressure liquid refrigerant output from the condensation device 20.The refrigerant tube at the output end of the refrigerant filter 40 isconnected to the refrigerant tube of the throttling device 50, and thethrottling device 50 decompress the medium-temperature and high-pressureliquid refrigerant filtered by the refrigerant filter 40 into thelow-temperature and low-pressure liquid refrigerant, and deliver intothe evaporation device 10. The throttling device 50 may be an expansionvalve or a capillary tube.

The fan 61 at the end of the condensation device 20 may be a blower. Theblower draws air in the atmosphere from the end of the condensationdevice 20 and sends it to the inside of the condensation device 20 forheat exchange. The heat-absorbed air is transported to the exhaust port103 through the ventilation tube 21 at the bottom of the condensationdevice 20, and then is exhausted to the outside through the exhaust tubeat the exhaust port 103.

In an embodiment, in order to accelerate the circulation of the insideand outside air and improve the heat exchange efficiency, a plurality ofventilation holes may be arranged on the housing (i.e., the housing 11(or the housing 19)) of the heat exchange structure of the condensationdevice 20.
